Numbers 18:1-3 New American Bible, Revised Edition (NABRE)

1. The Lord said to Aaron: You and your sons as well as your ancestral house with you shall be responsible for any sin with respect to the sanctuary; but only you and your sons with you shall be responsible for any sin with respect to your priesthood.

2. You shall also present with you your kinsmen of the tribe of Levi, your ancestral tribe, that they may be joined to you and assist you, while you and your sons with you are in front of the tent of the covenant.

3. They shall discharge your obligations and those with respect to the whole tent; however, they shall not come near the utensils of the sanctuary or the altar, or else both they and you will die.
